Lichen nitidus (LN) is an idiopathic, benign, chronic, inflammatory dermatosis that mainly occurs in children and young adults and generally shows spontaneous resolution. LN is typically characterized by tiny (1–2 mm in diameter), flesh-colored or hypopigmented (especially in dark-skinned individuals), asymptomatic, shiny papules, which mainly affect the abdomen, chest, extremities, and genitalia (especially in men), Dermatoscopic examination of LN generally shows smooth, roundish, homogeneous, whitish clouds (one for each papule) usually presenting sharply demarcated margins and often lacking physiological skin markings. When located on palmoplantar areas, LN lesions may reveal parallel linear scales as well as oval or elongated, well-defined depressions (pits) surrounded by ring-shaped, silvery white scales.
